The country with the most coal being used as an energy source is coming up with new ideas to fight the pollution, caused by coal combustion. Chinese and Italian Architects have developed a new building that is covered in shrubs and plants to release more oxygen into the environment and reduce greenhouse gas. “Once construction is completed in 2018, the structures will be able to absorb enough carbon dioxide to produce 132 pounds (60 kilograms) of oxygen.” - Futurism(Futurism ~ June JavelosaJavelosa). The Chinese government has also given Stefano Boeri a big project to design a forest city in one of the most polluted countries in the world. Countries are also introducing clean coal'clean coal' technologies which can help reduce greenhouse gas emissions and prevent acid rain from occurring, this. This technology has a thermal efficiency of 50%. More work is still required toon this tech to make it even more sustainable for coal power plants.
